A recent film titled Wandering … But Not Lost features Tibetan Buddhist Meditation Master Mingyur Rinpoche. In 2011 he left the security of his monastery to live the life of a wandering yogi. His wandering lasted four and a half years (through 2015) incognito on the streets of India, Nepal and in Himalayan caves. In this film, Mingyur Rinpoche returns to share the insights he gained.
